Gradle load properties from file and use it in liquibase task - gradle

Question

I am trying to load properties and use it in liquibase task. I am able to load the properties and able to print it out. But when I use it in liquibase task, gradle complains that properties are not found.
I am using:
classpath 'org.liquibase:liquibase-gradle-plugin:1.1.0'
Loading properties:
def springApplicationProperties = "src/main/resources/application-${System.env.SPRING_PROFILES_ACTIVE}.properties"
def springProps = new Properties()
InputStream is = new FileInputStream("${springApplicationProperties}")
springProps.load(is)
println "${springProps['spring.datasource.url']}"
Liquibase block:
liquibase{
activities {
main {
changeLogFile 'src/main/database/changelog.groovy'
url ${springProps['spring.datasource.url']}
username ${springProps['spring.datasource.user']}
password ${springProps['spring.datasource.password']}
}
}
runList = 'main'
}
And I am getting
No such property: $springProps for class:
org.liquibase.gradle.Activity
Looks like springProps is not visible in the liquibase activity. I tried to use ext and project scope, both not visible in liquibase block.

Answer 1

It will work this way:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'org.liquibase:liquibase-gradle-plugin:1.1.0'
}
}
apply plugin: 'java'
apply plugin: 'org.liquibase.gradle'
ext.springProps = new Properties()
InputStream is = new FileInputStream("src/main/resources/lol.properties")
springProps.load(is)
liquibase {
activities {
main {
url springProps['spring.datasource.url']
username springProps['spring.datasource.user']
password springProps['spring.datasource.password']
}
}
runList = 'main'
}
You unnecessarily added ${}. I've changed script a bit while trying out myself - but it has no side effects.
